This place is the bee's knees - my go-to for years. Yes, it's now $5.95 per item instead of $4.95 and it may not feature the best food you've ever tasted, but this is really great stuff considering you pay pennies for it.
Atmosphere - lively and upbeat with good music, a little hard to talk as it's pretty loud but that's typical of such environments anyways.
Service - not spectular, but not bad. There can be a long wait to get in (30-45mins being the worst I've faced, 5ish being the best) but the wait for food is not terrible (15-20 mins?) and the servers are friendly.
Food - really good if you pick right. The queso corn dip is a great app to share (comes with breadsticks!!!). Tomato penne is really, really good for a main course. I have not dabbled into the burger menu extensively but I tried the veggie burger once recently (Feb 2018) and it wasn't bad! Fries are good - super crispy. Portions are way more than enough (granted I'm 5'2 and don't eat a ton)
All in all, this is one of my favourites - really want to try desserts next time!
