I came away thinking that if you lived in the neighborhood you could do worse than El Jalapeno's but if you don't live nearby then no need to bother.
Now, the main dining room seems a little tired and worn but there's a decent amount of TVs (showing the Indians' playoff game the night we were there) and the wait staff was very personable. I had no complaints about the quality and quantity of the margaritas (and there are plenty of options) and the food came out very fast.
The menu looked quite typical with about 80 menu items and I was feeling hungry so I went with the El Jalapeno's Special which included five different items. The best of the items was the pork tamale. Instead of being served in the corn husk it came out like a pancake sitting on top of shredded meat. The masa bread was not too dry while the pork was mouth-watering seasoned which spurred me to not put my fork down until it was all gone. Meanwhile, the beef taco, beef enchilada and the chalupa (as well as the beans and rice) were all fine, I guess. Then there was the chile rellano -- since I'm a carnivore I passed it on to one of our dining companions but I kept the plate full of water that I assume came from the chile.
Again, if I lived in the area and came enough to pinpoint the best menu items, I think I could enjoy the place. But right now I'm just glad that I live in a neighborhood with a Cozumel's.
