I like this place (despite its flaws), and I eat there a few times a year. The sandwiches almost never disappoint - I am particularly fond of the kafta - and I always take some ayran with them. It's reasonably priced.
There are a few downsides. The small restaurant (3-4 tables) is sometimes hot and stuffy during the summer. The plastic tablecloths are not always cleaned after the previous customer. And the people working there don't smile too much.
It would also be nice to have a few tables outside too.
