This place is always busy when we go. I've been here 3 or 4 times because I love their Beef Fajitas, but the other things I tried (quesadilla, burrito...) were not that special to me.
The price is average for the area, I think my fajitas were something around 16,000won but I usually share it and order some appetizer, so it´s affordable for me.
The beef Fajita comes in a hot platter with onion an pepper, and a (too tiny) can of guacamole, salsa de tomate, beans, and melted cheese.
So even though I really like the fajitas, I´m only giving it a 3/5 because of the price and because the service is not that good. As I said, it is usually full, so they don't pay too much attention to you and leave you waiting more than needed.
But in addition to that, we were once 5 people and they wouldnt let us sit in a 4people table with an extra chair. They would also not let us seat on a big table because they said that's only for 6-8 people (we were 5, so almost 6... and it was 3pm, not the prime lunch time in Seoul, there were many small tables empty at that time) Also... there was ONLY 1 table that could sit 5 people, and it was occupied by a party that was still eating appetizers. Because we didn´t want to wait 1h and we were tired to find a different place, we splitted into 2 tables. Let me say something: I find this unnecessary and the waiters' response was really poor.
If their service was more attentive, I would give it a 5 smileys. But sorry, a restaurant depends not only on food!
