For this week's Patch Dining Debate, we asked readers to name their favorite Mexican restaurant.

Thanks to those of you who commented and told us your pick! This week, three restaurants were nominated:

• Guajillo Mexican Grill (Maryland Heights)
• Pueblo Nuevo (Hazelwood)
• Las Fuentes (Florissant)

You can cast your vote for your favorite among the finalists by submitting your answer in the poll below. Once you've voted click on your favorite restaurant and leave a review.

Voting will continue through Thursday, and ends at 5 p.m. Check back Friday morning to find out who has been chosen as this week's Dining Debate Champion for having the best Mexican food.

After you've voted, be sure to tell us in the comments' section below why your favorite is the best. And if you think we missed a great Mexican spot in this week's Dining Debate, let us know in the comments below!
