Go here all the time. All your favourite food in one place, perfect for occasions or a little treat! Not expensive considering it's a buffet, love it

Nice resturant, good value. A shame it's no longer open. Does anyone know what's happening? There is no information on the website, and it has disappeared from the parent group website.

I ended up in this dingy cellar for my birthday lunch because my mamgu liked the place. That makes no sense whatsoever, because it is truly awful. It is overpriced, claustrophobic, loud, of questionable hygiene, and the food is of a standard comparable to that of an especially bad takeaway.

Good place for large groups for birthdays or special celebrations. Lots of tables and room, and lots of food choice. Although it's got plenty of room, the food however is not that great in my eyes. It's also quite expensive!

People who diss cosmos obviously haven't been to Jimmy's. Coz once you've been to Jimmy's, then and only then, you can feel free by putting a bad review about cosmos. As you can probably tell me and the family didn't have a good experience there at Jimmy's. But decor was great! But can't say the same for the food/variety.

Been there a couple of times and the staff are always friendly and well-organised, there is one particular lady who handled our payment as we were leaving and she was lovely. The food has always tasted fresh and crunchy, and as it's not such a huge establishment, the noise level is acceptable. Slightly annoying that the bathrooms are all the... More
