We used to go to Taxi's a lot, especially since they had a deal where you got a discount if you bought and wore one of their t-shirts or got a free kid's meal if they bought and wore one of their t-shirts. Now it's "moms eat free on Tuesdays if you buy 2 entrees". (I'm not sure what an entree is there.) Also, they appear to have raised their prices. It was $20 for me and three kids. To upgrade your kids soda to a kids milkshake you had to *add* 1.99! Suffice it to say I won't be running back there. I like their grilled chicken potato when I do go there.
Another issue is the bathroom. It is outside, and you need a key. (Like at a real gas station I guess.) It's nice if you don't have kids to deal with and want to eat. The bathroom thing is really a deal breaker for me.
