I guess that I'm a fan of Sweet Tomatoes. It is a good meal for the price!
They email me coupons so we feel like we get a deal, each month they release new signature items and it's an all you can eat salad bar with soup and more. We couldn't prep all the things we love on our salads and eat for the price we end up paying.
The staff is attentive in clearing our plates as we finish them and nice so we usually leave them tips (yes, it's okay to tip someone working hard in a food establishment).
The only downside can be other patrons but you have to look past that when diniing at a buffet (it can be quite annoying or disturbing sometimes).
No matter what we will be back to Sweet Tomatoes for a "healthy: meal.
