I frequent the Taco Taxi on Lake Street quite often. Both the store and their taco truck. The tacos are amazing. They do a fantastic job serving food late night, especially after a night of partying.
With that being stated, I've been there a few times during the day, and I can't say I am pleased with the behavior of (what I presume to be) the owner. Tacos come standard with two tortillas, your choice of meat, onions, cilantro, salsa, and a jalapeno if you wish. Tacos at the store are $1.86 + tax, and at the truck they are $1.25.
My friend came into the store one day with his girlfriend and ordered 9 tacos. He was given 3 small (2 ounce) cups of salsa roja. He asked for 3 more cups of salsa because 1) he needed more sauce and 2) he really enjoys their salsa roja. The owner argued with my friend stating that you only get 3 and it would be extra for more. The owner reluctantly gave him the extra salsa my friend was asking for, with half filled cups.
I went into the store one time and ordered my standard 3 tacos. I always order my tacos with tomatoes and cilantro, with a side of red sauce, and a jalapeno. This day, I ordered an extra jalapeno. The owner told me that a jalapeno would cost extra. I guess I'm only allowed one free with my order. He charged me the price of a taco--$1.86.
I recently went to the taco truck where I ordered 4 tacos ($1.25) with cilantro and tomatoes, instead of raw onions because I don't like them. The owner charged me $7. I asked why I was being charged $2 more. He explained that tomatoes cost extra. I demanded my $2 back and just had him make the tacos with meat and cilantro. He went further in explaining that ordering a 'norte americano' taco would be extra. An american taco is a menu item of theirs. And it includes the works, onions, lettuce, tomato, cheese. I don't understand how I tried to order an American taco. I was merely substituting one vegetable (onion) for another. I don't believe that I was asking for more.
Maybe I'm overreacting to all of this, but I do think there is a limit to how much a business owner can nickle and dime customers. Are we going to get charged extra for using the 'allotted' amount of napkins? I guess if there is a resolution to this, I will refrain from ever going there during daytime hours. But still, I think this is poor behavior for any establishment.
