Boomburger was delicious, but not very big and somewhat overpriced for what it's worth. Music a bit too loud and intrusive. Would visit again, but won't make it a regular place.
The burgers are really good, but they do not comr with fries. If you order the "skinny" option you get nothing more than a patty. However, the burgers are delish.
Gotta say they know how a burger is done,but waitress is a bit impolite and foreign language is definitely not part of her CV, we had bit of troubles ordering
I cannot believe this place exist in Sofia. I am a cheeseburger fan, which is flawless & simply excellent. Meat tastes like you could not have imagined! Oh, almost forgot - try the cheesecake - mmm!
Too expensive - 18 BGN for a burger for without a side dish. Service is slow and the place looks like a cafeteria. I will not deffinetely make the mistake to visit this place again.
Realy great burgers. Tried cheeseburger, boom and fillet burgers - all delicious. To be sincere, I didn't expect such quality from the burger joint in Sofia. Recommended
