Mahabaleshwar is a cool option. The serenic beauty will amaze you also for food you can go to Maori garden which is a pretty good place to hangout and chill and also the yummy food with a view!
If you are looking for adventure as well as some leisure time I have the best option for you..... Check out Bhandardara, dist. Ahmednagar. It's an amazingly beautiful place. It's one of the best place you can visit and chill for 1-2 days. There's mountains all around. Bhandardara is situated in the midst of Sahyadri range. You must visit this place once at least.
