This chain has certainly changed over the 15+ years I've been going to it... the prices have gone steadily up, the portions gotten steadily gotten smaller (particularly if you go downtown). On a personal level, the ribs and fries remain favorite meals and every few months I find myself going back for one of my favorite meals. The chicken tenders are great as well.
The service is polite, almost robotic as waiters rarely have a moment to talk with their guests yet are always more than available for refills, asking you how you like your meal exactly 5 minutes after the food is served (yes we timed this once). They are competent and work towards serving you efficiently and quickly so that the next client can get to their seats.
The line-ups during peak hours can get pretty ridiculous. Expect to wait an hour if you visit between 6 to 9.
I like the ambiance of the place, decorations are warm, colors are suitable and seating comfortable.
As mentioned before, the baby back ribs are excellent and the fries usually well done. The chicken tenders are usually good but sometimes are hit and miss as they put too much batter.
I've also had several different meals in the past, such as their burgers and salads which were very good.
Sodas are now fountain based down in quality of the bottles of old and can be watered down at times. Refills are free however.
