If you're looking for tasty, authentic Mexican food, 'on the cheap' near Purchase College SUNY, and you don't mind dining at a 'hole in the wall' type of place, check out Las Brisas located 15 minutes from Purchase College. (Las Brisas, 215 Westchester Ave., Port Chester, NY, 914-937-1462)
Its 'dry-erase' menu, dingy pink and gray tiling, foggy mirrors and beat up tables are not pretty but their food is great! If they bring you refried beans instead of black beans or vice versa, keep it, chances are that you'll like it anyway. To avoid this, know exactly what you want at the time that you order and try not to change it midway through ordering.
I usually get a Burrito (Burro) with chicken, black beans and rice with red sauce which I've circled in yellow on the menu photo below. Have you ever eaten there? Share your experience.
