Hello. #19 and #18 are a bit too plain. They don't pop enough, either with the color or the symbols. #16 is too similar to Chili's restaurant. If you can work on other icon ideas and different color combinations that would be good. Thanks!
#55 is better. Can you perhaps try to add more pizzaz? Perhaps color changes or a bit more in the logo? It's getting better, but still looks a bit plain.
