I went to Leña with a group of colleagues this past week.
What a let down.
1 - the service was slow beyond belief.
2 - the food was good overall - but slow coming out.
3 - there were a group of servers helping - but no one really took the lead, nor checked in to see how we were doing.
4 - at one point, they wanted to clear the table while we were still working on what was (still) on the plates.
5 - they forgot a couple of items.
6 - the waiter brought over two double espressos, one of which had one ounce of liquid in it. He tried to convince me that the cup with one ounce of coffee liquid was also a double espresso. I was baffled.
7 - the coffee is as bad as it gets.
It's too bad - it's a really nice looking joint, with decent food.
It could (and should) be amazing.
Avoid.
