The Duke of Cambridge sounds like a pub, but don’t let that fool you.

If you do, then you’ll end up feeling like my friend did last Saturday night. And that is like a prize plum.

I was sitting near the back of this rather special bar with two amigos, while arguing bitterly about how to pronounce the drink ‘Bourbon’. Do you pronounce it Berbon? Or is it like the biscuit? I won’t divulge which corner I was fighting for!

The argument was won by the most coherent party member, then we realised it was time to head back to the bar to replenish our glasses. So off we went, leaving behind the most intoxicated of the group to guard the table like a ferocious Doberman.

The cocktails in this place are superb. And so they should be. It’s certainly the plushest cocktail bar that I’ve been to in Oxford, beating Angels, Cafe Baba and Sugar Brown (to name a few) hands down.

It took me back, inside my fantastical imagination, to Tretters Cocktail Bar in Prague’s old town. Not so much in looks, but in ambiance, skilled mixologists and taste.

I went there with friends a couple of years back, and the place was so popular that you had to book a place to stand at the bar.

Obviously we didn’t think that far ahead, so were politely shoved in the back room (which was the walkway to the toilet with a couple of tables squeezed into a space reminiscent of a feng-shui approved cattle market), but we were grateful anyway to be seated in the same bar as Prague’s elite.

I could see the same system possibly being employed at the Duke of Cambridge — every table was taken, and we were lucky to find one.

My Doberman pal made the mistake of moving to the door to have a cigarette and upon looking back he saw a couple of posh table vultures diving into our seats.

The swines. Standard cocktails are £6.50, so start saving now, kids. The taste, however, will convince you that it was worth the money.

It has to be the taste that keeps people here, because it certainly isn’t the generous servings of booze.

Enormous glasses are used to hold the cheeky cocktails, but the barmen meticulously measure out a 50ml double measure for each one with the precision of a German car manufacturer.

Most £5 cocktail bars will simply free pour. So judging by the strict measures, the price of each drink and how damn popular the place is with cash-flashing rich lads and ladies — the Duke of Cambridge owner is laughing all the way to the bank, which is probably Coutts of London, so that’s a whole lot of laughing!

The mate who I charmingly described as a prize plum, turned up to the Duke of Cambridge a bit later, without having been there before.

I said last week that dressing up is a must, but he turned up wearing ripped jeans, baggy hoodie and Converse trainers that smell exactly like Sardinian Casu Marzu maggot cheese.

Needless to say, he felt more out of place than Jade Goody in the centre of New Delhi. Smart dress only, boys and girls, you have been warned — but if you haven’t been there already, it is now essential to do so!
