Recommendations and pricing for marriage halls/lawns in Lucknow

Hi everyone!

I have gone through the subreddit's earlier posts and recommendations.
I'm looking for a wedding lawn with covered area as well, for men and women, with oriental/traditional decor for a wedding reception ("waleema").

We do not need hotel rooms for accommodation(since this is a local wedding), but a covered area for dinner and shelter in case of inclement weather.

Could our Lucknowi people in the know suggest some good venues along with the on-ground prices?
The kind of places we like based on online photos are Moti Mahal Lawn (Richi Rich), Balrampur Gardens, Moti Mahal Lawn (Royal Cafe) etc. We are being quoted prices in the vicinity of 6.5 lakhs for one day, for a function of around 500 guests.

I would really appreciate if you folks could chime in based on your experiences and contacts.
Shukriya!
