Squalo Vino has been pouring wine on Main Street since 2021, which makes this fall the start of its fifth year in business, tasting flights, Wine Shark merchandise and all. A few miles up Tiburon Boulevard, in the Cove Shopping Center on Blackfield Drive, Mog Asu Wine Bar is still settling into its second year, young enough that regulars remember when Fedric D'Costa and Emily Lund poured their first glasses back in February 2025.
Two dedicated wine bars on one small peninsula sounds like a crowded market chasing the same crowd. It isn't. Squalo Vino and Mog Asu opened years apart in two different commercial pockets of town, and neither one is trying to be the other.
The Main Street Bar Built for the Ferry Crowd
Squalo Vino sits at 34 Main Street, close enough to the ferry landing that a Golden Gate Ferry passenger can walk off the boat and be seated within a few minutes. The list leans toward the wines a Marin regular already knows how to order: Napa, Sonoma, Bordeaux, Champagne, more than 80 bottles deep, with a rotating by-the-glass selection built around an "old world versus new world" framing. The Wine Shark branding is a little playful for a bar this serious about its inventory, but the Whale Shark membership tier and quarterly wine club shipments say the real business model is repeat customers, not tourist walk-ins.
Hours matter here in a way that's easy to miss until you've shown up on the wrong day. Squalo Vino is closed Monday and Tuesday, and on the days it's open, it closes at 8pm during the week and 6pm on Sunday. It's a bar built around an early evening, the kind of stop that fits between a ferry commute home and dinner reservations elsewhere on Main Street.
The Cove Bar Built Around What Main Street Doesn't Stock
Mog Asu is a different proposition entirely, starting with geography. The Cove Shopping Center sits off Blackfield Drive, closer to Blackie's Pasture than to the ferry terminal, in a part of town that doesn't see the same foot traffic as downtown. D'Costa, a Level One certified sommelier who spent years at Cavallo Point before opening his own place, built the wine list around regions Main Street doesn't typically carry: Portugal, Spain, Greece, alongside smaller producers from France and Italy. Thirty wines by the glass rotate regularly, backed by 60 bottles, and the name itself, Konkani for "let there be love," reflects D'Costa's roots in Goa.
The hours run later than Squalo Vino's. Mog Asu stays open until 10pm on Wednesdays and 11pm Thursday through Saturday, with Sunday bingo at 7pm drawing a regular crowd. It's closed Tuesdays, the one day both bars sit dark, but otherwise it's built for a longer night than its Main Street counterpart.
So the choice between the two isn't really about which one is better. It's about what you're doing that evening. Stepping off the ferry and want a glass before dinner reservations at 6? Squalo Vino is a two-minute walk. Looking for a later night with an unfamiliar Portuguese red and a seat that isn't packed with day-trippers? Mog Asu is the one that's still pouring at ten.
A Festival That Was Decades Ahead of Both of Them
None of this wine culture is new to Tiburon. The Tiburon Wine Festival returns this year for its 43rd annual run, on Saturday, October 3, at Point Tiburon Plaza, hosted by the Tiburon Peninsula Chamber of Commerce. Roughly 65 wineries will pour alongside a restaurant lineup that reads like the town's own dining directory: The Bungalow Kitchen, The Caprice, Woodlands Market, Malibu Farm, Luna Blu, Salt & Pepper, Petite Left Bank, Tiburon Tavern, Jane the Bakery Marin, and Trattoria Servino. It's a ticketed, 21-and-over event, rain or shine, and the Chamber points out that the smartest way in is the Golden Gate Ferry, which departs San Francisco at 12:15pm and lands festival-goers steps from check-in by 12:45.
A festival with more than four decades behind it means Tiburon was already a wine town before either bar existed. Squalo Vino and Mog Asu aren't creating a new appetite. They're building the daily infrastructure for something the peninsula has been proving one Saturday a year since the 1980s.
That's worth sitting with for a second, because it flips the usual story about a "wine bar boom." The bars didn't arrive and teach the town to drink wine. The town had already spent forty-some Octobers doing that at scale, and the bars are what showed up afterward to make it a Tuesday-through-Sunday habit instead of an annual one.
What This Means for Your Week
If you're deciding where to spend an evening between now and the festival, the geography does most of the deciding for you. Living or working near downtown puts you close to Squalo Vino and its early close. Living closer to the Cove or Blackie's Pasture side of the peninsula makes Mog Asu the more natural stop, especially on a night when you want to stay past eight.
Local coverage has described Tiburon as a town "booming with wine bars, five at last count," which suggests Squalo Vino and Mog Asu are the two most documented anchors of a wider shift, not the whole story. Whatever the other three turn out to be, the pattern so far holds: this isn't one street getting crowded with lookalike wine bars. It's two different parts of town, each generating its own answer to the same demand the Wine Festival has been proving for over forty years.
With the festival landing October 3, this is a reasonable week to figure out which bar fits your evening before the plaza fills up with 65 wineries and a ticketed crowd. Squalo Vino if you want familiar bottles and an early night near the water. Mog Asu if you want something you haven't tried yet and don't mind staying out past nine.
If you're the kind of Tiburon resident who tracks which storefront changed hands on Main Street or which shopping center just got a new tenant on Blackfield, that instinct is exactly what Smith & Co. pays attention to as well. We're happy to talk wine bars, the Wine Festival, or anything else that's changed on the peninsula this season, no listing required.
