Do you mean Le Meridien at the airport ?
If so, you have Festival City mall close by (10 minutes by cab) this has a canal running through it with restaurants on each side and a gondola - very lovely it is too.
Much further away (30-40 minutes by cab) is the Madinat Jumeirah complex. This is set round a range of waterways and has abra boats to transport residents around the complex. Lots of the restaurants are by the water.
Dubai Marina area is 40 minutes away. This is a yacht marina so no gondolas. It has restaurants around the marina.
If you are at Le Royal Meridien then Dubai Marina is over the road, the Madinat is 10 minutes away and Festival City is 30-40 minutes away.
All of the restaurants everywhere will be open after sunset.
One other thing to bear in mind is the heat and humidity, many places will have their outside terraces closed
