Chili’s complaint: Terrible experience!!!!!

Dear Mr. Kevin Hackman,
We have been a customer at Chili’s at the Downers Grove 60516 Il, location probably since opening date, 15 to 16 years ago. Usually going to eat here once a week. Today, we have what I will say the worst experience ever, at this location. Let’s say we always choose the bar area for dinner, because it always has been fun, versus the main area (For us). Today… Beginning with the Frozen Margarita. Let me told you. I have been ordering Frozen Margaritas for ever at Chili’s, what it was brought to me was not a Frozen Margarita, it was a glass fill with what it seems left over from a bunch of Frozen Margaritas. You know, what is left in a glass after we drink one.. ( if you drink Frozen Margaritas you would know), yes that Frozen part that is left on the bottom of the glass. Yes that! When, I returned it, the bartender (not the server), came to ask me what would I like to drink… I explained a Frozen Margarita, but not the one brought to me. He stated that what they brought me was a Frozen Margarita. Interesting!! Perhaps insulting. Bartender, also stated that they just got a new Frozen Margarita machine. Ok. If the machine is not working properly why this Chilis’s is trying to sell Frozen Margaritas today. We are not heavy drinkers, we drink a drink, usually a Frozen Margarita, but if the machine is not working is fine, we would choose something else. Other issues.This Chili’s in Downers Grove seems be changing. We were advised that our favorite server and bartender Andy quit. (He was there probably at this Chili’s for over 10 years. Andy knew our names, Andy knew everyone’s name, knew everyone’s drink orders by heart, our food preference , etc. Andy made this Chili’s awesome, this Chili’s was different and really great.) Today at this Chili’s, the staff was extremely young, inexperience, our server was new. (They) the server came to our table, what it seemed 20 times, coming from time to time to check is great, coming 20 times not great. (They) did not know or notice any issues with my drink, inexperience perhaps? The bartender should have noticed. The entire experience was not fun, the bar area is boring now. it seems no one is interested on the customers having great time. We got no Frozen Margaritas, no great service, not a great time, food was good . Yes, we did talk to the manager (General Manager he explained), he also explained the issue with the Frozen Machine. Please, we would like to ask for Mr. Kevin Hackman, to please take another look to the changes at this location. No just the drinks, is everything, the feeling of “what ever “. is not right. We are regulars at this Chili’s, we like it here, or we did. Being a great place is the difference. Thank you. We appreciate your time and consideration. BA
