First time visitor.

Hey everyone. Visiting lucknow for the first time. Don’t know anything about the city. We’re there for two days but looking to make a day trip to Ayodhya for one of the days. (Any tips on best way to get there?) So the time we’re in Lucknow I want some recommendations on which area to stay in and where to eat the best lucknavi food (Biryani / Kababs). I’ll say we’re not from India and a bit sensitive about the hygiene so want the place that’s clean and good that’s not too spicy. Our tummies can’t handle it!! lol. Thanks in advanced!
