Ranjit's for North Indian food. Go get a thali (full meal) or snacks like pakoras, samosas. It's our favourite place in Glasgow. Another good place is chakoo.
Rishi's is good for South Indian food like dosas and idlis.
Definitely go to Ranjit's if you haven't already! Feels so homely because you can catch glimpses of aunty and uncle cooking in the kitchen and the food tastes amazing and homemade.
