I had to go away from the London office to the Birmingham office for an away day recently. Yeah one of those forced enjoyment things...
So we had a poll to decide what to eat that night and we decided on Dishoom. I've been to Dishoom a couple of times in London and found it edible.
When I went and ate there this time, honestly, I ate it because I was hungry and we'd booked the table but I thought it was awful, especially because there are so many nice Indian restaurants in Birmingham. What also stuck in my craw was about £10 for a gin and tonic! 
So is this a one off bad experience? Have they gone downhill? All my colleagues were raving about Dishoom.
