Spicy tofu is different from Mapo tofu. I have been in Sichuan for 4 years, and all the spicy tofu I have eaten is moderately spicy. I may have heard that it was a foreigner, so I didn't put so many peppers. As for Mapo tofu, I remember the first time I ate it, my throat was itchy and I couldn't drink water. Mapo tofu is not spicy, but hemp. I can't stand it the first time. And there are some minced meat in Mapo tofu.
In my place, spicy tofu is a vegetarian dish and Mapo tofu is a meat dish, so the price should be calculated according to the price of meat dishes.
