This is the view from the other side, there is a long bar where you can hang out if you don't have a reservation.
The night we went, there was a band from Holland playing, called the Agog Trio. They had a nice chemistry between them, and came across as a team of friendly, energetic, experimentative players.
The food isn't really anything great, I tried some starters and gave up midway. My Thai Mojito had an interesting kick with ginger and coriander, but it was cloyingly sweet. The service was absolutely super, though.
The Blue Frog is more than just a restaurant that plays music. They have four sound recording labs, as well as music production facilities. They help launch records and they offer artist management services. Quite a welcome addition to the city's music scene.
The May program includes performances by both Indian and internatonal artistes. There's Pratz and the Blues Band from Calcutta, Montreaux Jazz Fest winner Leo Tardin, the interestingly named Silverchops (a jazz band from Pune), Alisha Bhatt (punk rock), Aurora Jane from Australia (funk rock with aboriginal twists), Cap'n Crunch (Mumbai-boy Floyd Fernandes plays what he calls "electro-jazz and clubtronic fusion", whatever that is!), and lots more.
Go check it out. I'm definitely going back there again.
