We've had places for only fries, only littis, milkshakes, waffles and so on. Here's another one to squeeze into that list of yours: Burger In Law in Salt Lake.
The two-page menu has one dedicated to just burgers, and we are loving the names -- The Couch Potato has a potato patty, grilled pineapple, caramelised onions and cheese slices, while La La Lamb has a minced mutton patty, coleslaw and cheese slice. Aren't you drooling already? It has a selection of add-ons such as mushroom, bacon, eggs, etc. You'll also find a series of 'Jawbreakers' which include those huge burgers that you wish you finished under three minutes -- starting at just INR 380. Apart from burgers, the menu lists sections to iced beverages (because no one likes their burgers dry), elaborate house salads, mains like Cottage Cheese Steak and Grilled Bhetki and an array of sides, i.e., french fries and more.
This little outlet is winning our hearts super quick because we don't see anything that we don't like about them, specially that you and your bae can easily have a full meal for just INR 500.
