We are doing our menu tasting with our venue next Thursday evening. Our venue is all inclusive with catering/bar/DOC etc. and our venue pricing includes service charge (gratuities per our DOC at the venue). We are still going to tip during the tasting as I think that's only fair as the chef is providing us this additional service to preview our menu. My question is how much do we tip for this? It's going to be myself, FH, FFIL&FMIL, as well as his two sisters/bridesmaids. Since we're sharing 6 entrees to taste, how should the tip be applied here? I normally do at least 20% regardless of where I go but I have no set bill or price point to go off of for the food pricing on average as our pricing includes all of our extras. Any ideas?
