There are so many choices of meats offered at Taqueria Apatzingan that you'll have to come back again and again to try them all. That includes the birria Mexican meat stew and lengua, or ox tongue, for those with more adventurous palates. Open early for the breakfast crowd every day of the week and nestled in the heart of a business district on Middlefield Road, Taqueria Apatzingan is a favorite among locals and travelers alike. Se habla Español, but you don't need to order in Spanish to get a great meal at one of the best, authentic taquerias in Menlo Park and beyond.
