It's acceptable. I went there before noon, so I didn't experience lines or anything. It certainly took some time to have my order ready (like 25min) and the fries were overcooked. The burger was good (nothing special). The place doesn't look good, though - they should work on the decoration. It's not very well-lit and looks a bit dirty. It's a shame, because the attendant was pretty polite and in good spirits.
I can see being an inconsistent experience, though, depending on size of lines and time of the day. Doesn't have lots of tables for large groups, too.
