It was my first visit on an absolutely beautiful day of weather for mid December! We did have a large group at our table & I realize how difficult that can be! With that being said I was treated very rudely by our waiter & any attempt I made at correcting whatever might have caused the rude behavior was met w/what I felt was mild contempt!! However the food was simply divine!!! Authentic Italian food at its finest!!! I started with a charcuterie board & there was plenty to share around the table. Someone also ordered calamari & oh my - by far the best I have ever tasted!!! When it came time to place our entrees I asked to have just the calamari. As everyone's meals began arriving, w/mouth watering aromas, I was anticipating my calamari. I waited & waited but nothing came!! I asked about it & the waiter said, "Oh you wanted calamari? Let me check on it." I waited & waited, still nothing!!! I finally asked our busser, Angel, (who was excellent at his job & his level of professionalism & customer service was well above my waiter) who said he would check on it. The order had just been placed so I would have to wait a few minutes!!!! Very frustrating & totally uncalled for!!!! They were out of my most favorite dessert, creme brulee, so I had a vanilla bean ice cream which tasted yummy!!! Again I know I was w/a large party but I was the only person treated in this manner; not something I'm used to. I did ask that he not pour my entire bottle of beer into my glass all at one time because I prefer to keep it in the bottle so it doesn't get warm if I'm not drinking it quickly. Sorry if that insulted my waiter. Other than that I had a perfectly wonderful evening at Renato's & will definitely visit again! My tip on my credit card bill reflected my mood but I also understand the restaurant industry is struggling, hence the cash tip which I felt was more than generous.
