Errr I'd have to disagree slightly. Have eaten at Firestables and while its nice I would say there are better...
Depends on what exactly you're after, there's different takes on "Gastro Pub" these days.
At the upper end of the spectrum you have the Gordon Ramsay "The Grapes" between Wapping & Canary Wharf and also "The Gun" which is famous for its Sunday Lunch. You can sit outside with the Thames only inches away.
At the more wallet friendly, relaxed style you have places like the "Jolly Gardners" in Putney which has amazing food, sundays used to have a live DJ playing an ecletic mix of downtempo music and also board games to while away the hours. Be prepared for a wait though as there's no booking system just arrive and wait to grab a suitable table.
You have plenty of other places dotted around. The Earl Spencer on Merton Road (Wimbledon / Wandsworth) Has won loads of awards for Londons Best Gastro Pub over the years although I found the atmosphere a bit cold... Had some great meals in West London along e High Road Brasserie on Chiswick Hig Road (celebrity owned again) was top end, as was The Ealing Park Tavern and the Rocket in Acton..
Plenty of choices, just depends where you're staying at what kind of atmosphere you're after! almost 10 years ago
