i bought 2 dineout coupons which said 50% on total bill. we settled in a nice place. the waiter comes to take the order, i said about these coupons, he hurriedly runs somewhere to check with someone. comes back saying it works only on indian liquor. we asked for some indian drinks. after a while he says it's not available and then we changed to some cocktails. again he ran back and comes saying they don't have any indian liquors and serve only foreign ones, but have kf pint alone and not even full. by then it was already 20 min. with a complete mood off we ordered few pints, a mex tex platter, chicken pulao and a taco. the platter came after 40 solid minutes, and the rest followed in 15 min intervals. the worst part is i could see some indian liquors and full beers were served to other tables. what a cheap business trick! also the 50% wasn't taken for the platter. the waiter didn't tell while taking the order. service is extremely worst. the food wasn't that great.
if you're not comfortable partnering with dineout, then don't. why do you want to embarrass the guests and ruin their evening!
