Green Park Brasserie
Green Park Brasserie runs its bottomless brunch every day of the week, not just weekends, which makes it one of the more flexible options if you want a midweek celebration. It's two courses plus bottomless drinks for £39, over a 90-minute sitting, with last bookings taken at 3pm. The setting is part of the appeal here: the restaurant occupies Bath's old railway station building, a genuinely striking, historic space rather than a generic bar fit-out, and it often runs live music too.
Thaikhun
Thaikhun's Thai street food bottomless brunch is the most clearly tiered of the group, so you can choose how much you want to spend. One course with unlimited drinks (prosecco, bottles of Singha, and a choice of cocktails or mocktails) costs £35pp, two courses £45pp, and there's a lower from-£30pp entry point too, plus a dedicated alcohol-free version if part of your group isn't drinking. The 90-minute session structure is the same as everywhere else in Bath.
Las Iguanas
Las Iguanas brings a Mexican and South American spin to the format, with its bottomless brunch priced around £45 per person. It's a regular feature on hen party planning sites, so expect a lively room rather than a quiet sit-down brunch, and book early if you're planning a weekend group celebration since slots go quickly.
Sub13
Sub13's brunch leans into the party side of bottomless brunch rather than a conventional sit-down meal: it opens with a free round of shots and a round of Porn Star Martinis, then runs bottomless cocktails alongside half a margarita pizza each person. It's aimed squarely at hen parties, birthdays and group bookings rather than a low-key catch-up, so pick it if that's the vibe you're after.
A few things to check before you book
- Confirm the session length and last-booking time. Most run 90 minutes and the clock usually starts from your table being seated, not from when you arrive, so turning up on time matters more than it sounds.
- Ask what's actually included in "unlimited drinks." It's usually a set list (prosecco, a house cocktail or two, sometimes bottled beer) rather than the full bar, and premium spirits or wine upgrades are typically extra.
- Book well ahead for weekends. Saturday and Sunday slots at the venues above are popular for groups, and the best times go first.
- If you'd rather have a calmer brunch without the bottomless element, our guide to the best brunch in Bath covers sit-down spots from the Pump Room to Timbrell's Yard, which suit a quieter morning better than a 90-minute drinks session.

The bottom line
For a flexible, any-day option in a genuinely striking setting, book Green Park Brasserie (£39pp, 90 minutes). For a tiered, Thai-food version with an alcohol-free option, go for Thaikhun (from £30pp). For a livelier hen-party or birthday crowd, Las Iguanas or Sub13 suit the brief better. Across all of them, book ahead, confirm what's actually included in your unlimited drinks, and expect a 90-minute sitting rather than an open-ended afternoon.
