Stayed there in November 2018. Food options for breakfast included a decent buffet, some hots, turkey sausages/bacon, potatoes, fruit, pastries etc, but eggs/omelette etc can be had to order. We found it plentiful and more than enough to get you to mid afternoon.
The "Afternoon Tea" 3-5 I think was just a few pastries and some fruit.
Evenings consisted of mostly finger food, Chicken Wings, skewers and the like, pastries/fruit again.
Alcohol was in plentiful supply, but waiter service. However the odd 5 or 10 dirhams now and again seems to keep you well supplied.
Lounge is nicely presented, some soft lounge furniture and private tables, with maybe 4 - 6 private tables for 2 overlooking the creek.

I am Radisson Gold however, so wouldn't have been entitled to free breakfast, you do get an upgrade if available, but most likely not to an Exec room for Lounge access. But some Radissons DO allow you to book an Exec room for extra points, a "Premium Room Reward".
I was able to book a Premium Room Reward in Deira Creek for 4 nights (66,000) per night, which gave me an Exec Room, breakfast, and lounge access.
However THAT was in November. I'm back in Dubai in a few weeks and given Radisson had a points re-shuffle last month (some hotels went up a category, some went down), I looked for the same deal again. I was initially delighted to see that Radisson Deira Creek had dropped a category, and a Premium Room Reward had reduced to 57,000 points!

BUT, on closer inspection, although a Premium Room Reward reduced in points, it now gets you a SUPERIOR room, not an EXEC room!! All you will get now is a bigger room, no breakfast, and NO lounge access!

Aside that, the hotel is actually part of a larger complex, and on the ground floor there are a large number of restaurants to choose from, Thai, Indian, Arab, European, Japanese, you name it! We had a few meals at the Thai and it was excellent, and very reasonable!

However, given the reduction in the Premium Reward we have moved our stay this time about 200 metres up the creek to Hilton... and we'll just walk to the Thai :-)
