I wouldn't think any of those to be inappropriate even in a busy bar. Aviation is a bit tricky as it requires fairly expensive ingredients. But they last a long time and go a long way.They are my normal go to cocktails to make at home. I don't think any are hard to make.A Ramos Gin Fizz is my hallmark pain in the butt drink. It requires 15 minutes of shaking. I don't make them at home, but I tip like crazy if I order one out.As I'm not a bartender, I'll leave the last question to others l.I'll give you a random recommendation. Serious eats has a recipe for the ultimate Paloma. Make it. It's my favorite summer drink. It's also easy to batch.
