I went with a group of friends last weekend. At first everything was fine, good music and good atmosphere. However, a couple of hours later they changed us because the place they had given us was already reserved, and they took us to a place a little further away. A little annoying, but in return the house invited the whole group to have shots. There was friendly treatment from the waiters who served us.
I have seen that there are usually a lot of problems with reservations, but otherwise (personally) fine.
