I really liked Lola's. I wanted to hit up all the Triple D's in the area and Lola's was on the list. I am not sure how "authentic" the n'awlins fare is (and I've been to NOLA) but the ambiance is nice, the waitstaff is pleasant, and the food is great.
I had the gouda grits and the roast beef po'boy. When I was in New Orleans in the late 80's, the po'boy seemed to be a gimmick offering that was all about just making a huge, almost un-finish-able sandwich piled so high with meat that you could not even get your jaws around.
At Lola's, the sandwich is more about making an amazing tasting sandwich vs just a huge sandwich. It is covered in a heavy gravy and stuffed with high quality ingredients. It was extremely tasty and I finished the whole thing (unlike po buys I had in NO). The gouda grits were great, nothing like the typical bland grits (sorry, southerners) you get most places. The cheese really makes this dish pop.
Since I was travelling for work, I was only one person and they sat me in a little 2-seat table by the 'bar', which was perfect for me.
I saw Lola at the door, greeting and saying goodby to customers, which was nice. I saw one lady with a midwestern accent telling her "I saw you on TV" and she was very nice and accomodating to all of the guests.
I would definitely come back. In fact, I debated coming back for a 2nd trip during my week+ in Vegas, which is a rule I almost never break (I try to sample a new place every night and not go back to any place I've already tried). I want to try something with shrimp next time...
