Apologies if this has been covered already, but there appears to be an Argentine Grill http://www.constancia.co.uk/ opening soon on the corner of Tower Bridge road and Tanner street - next to the Costcutter.
I thought these would be offices (under the new flats) but it seems it will be a restaurant. I'm partial to a nice steak myself, and it's a stone's throw from me, so i shall be watching closely. I like to support local businesses.
If the owners read this, please give some more information on when you intend to open and the menu. If the steak and wine is good, i shall be a regular.
I do love the Argentinian steak from Gaucho Grill. However, it does seem crazy that they import the beef all the way from Argentina. This can't be sustainable - think of the air miles involved in this.
Sebastian - are you planning on using British meat? I know that the South Americans like to cut their meat differently (they cut the Sirloin differently from the normal UK cut) but surely you can find a good supplier who will grow, butcher, hang and cut your meat as you require it?
Argentinean Beef is available here and in Europe because the demand exceeds the supply. Argentina is basically a primary products exporter, and two of the finest Argentinean products that can be found are beef and wines. In Constancia we will have both. It is also true that there is great meat in the UK and Ireland, and we are considering to also offer this alternative in the future. Argentina also imports many products and services from European companies, and the Balance in the trade should be something good for everybody. I don't want to turn this into a long discussion, but I would not mind to do it if we had a glass of Malbec in our hands.
Regarding prices, since we are a small, friendly, local restaurant, they will be more accessible. People are welcome to come just for a glass of wine and some "empanadas" (argentine style pasties), or go all the way and have a "parrillada" (brazier) with two cuts of beef, argentine style sausages, black pudding, and grilled cheese. We have other pleasent surprises in the menu, but you have to wait a little.
Having been to Argentina last year I am really looking forward to you opening! It sounds like your vision of good food at reasonable prices should be a winner & will hopefully be popular with locals & tourists. Good luck !
