Which company is good for dosa tawa?

Excuse me, could you please elaborate on the context of your question? "Dosa tawa" typically refers to a cooking utensil used for making dosas, a popular South Indian dish. Are you asking about which company manufactures high-quality dosa tawas, or are you looking for a company that serves delicious dosas? If you're seeking a recommendation for a company that produces durable and efficient dosa tawas, I would suggest researching brands that specialize in kitchenware and cookware. Look for companies with a good reputation for quality control and customer satisfaction. On the other hand, if you're looking for a restaurant or food outlet that serves delicious dosas, I would recommend trying out local eateries or restaurants that specialize in South Indian cuisine. You can also check online reviews and ratings to get an idea of which places are popular and well-regarded. In either case, I hope this helps clarify your question and provides some useful guidance.
