I generally know if an Indian restaurant abroad has flavors I like if they have lime soda (sweet or salty). Salty soda is amazing and I always order it. I wish we had salty sodas elsewhere.
The logic being, if they only offer sweet soda then they are catering only to people who like sweet sodas, which isn’t going to be the right flavor profile for me. Also having both is expected at most places
Even better if they also do homemade lassi (sweet or salty). The commercially made lassi here is rather revolting
