domain LondonTaste.com

It would be excellent brand for a fast food restaurant. Nice domain, your one of my favorite domainers. I can say four figures for the right user.

I think this one is really good! Can see it as an upmarket restaurant review site or better still a discount card for top London restaurants.

Not bad, but not easily sellable either, IMO. In the first place, the co.uk is available, so a buyer may prefer that one for reg fee. You also have to fight against alternatives (the plural, a prepending "the", "Of" London etc). There are 2 comparable sales, ChinaTaste.com and TexasTaste.com, both for mid 4-figures. In the past, there existed a company with that exact name, so that would be a plus.

yes good domain

setup a journey to the best london restaurants
.. if there are any

TasteofLondon.com would be the one to own and have some value IMO.
LondonTaste.com hmmm don't see much commercial value if any sorry.
It's actually harder to sell a .com to London based biz bc they prefer the .co.uk instead.

I do. A review /guide to dining. London obviously is huge and if you wait I'm sure you'll get a nice chunk/
