So I've been to Le Blokk twice. Last time when I vistited Marrakech in 2011 and most recently in June 2013.
The venue is lovely. The location may be a little far out if you're staying in the city however its not 'that' expensive to get a taxt to the plamarrie area.
I had the steak on both occasions and it was soooo tasty. I am a regular diner at Gaucho's and other argentinian steak houses in London. I'm fussy.
I wife has a Gluten allergy and so I showed the manager a card we take with us that explains it in French and Arabic (so much easier). They were very careful with her food and really looked after her.
On both occasion I booked a table there for 8'ish however we were the first ones there both times. If I were you, unless its a weekend as I heard it gets really bus (thurs, fri & sat) then I would book a table around 9, 9:30..
Long story short, great place if you life a decent fillet of steak.
2 glasses wine, 1 cocktail, 1 coke, 1 starter, 2 steaks with sides, 2 deserts - £65!!!! Unbelievably well priced for the place! That meal could easily have been £150+ elsewhere!
Keep up the good work and we WILL be back next time we're in Marrakech.
ps.. there is LIVE JAZZ MUSIC!!
