I have been to Jacob twice and had mixed experience - first time I would give 2 stars and second time 3 stars. Basically, I feel the quality of the food and especially the steak is still not as refined and lack the 'oomph' I often get at steak houses in the US- Chicago Chop House, Gibsons, Prime, St. Elmo, Peter Ludger, etc. And the service at those restaurants are almost over the top. And their steaks are always 10/10.
However, dinner this time at Jacob was splendid - attentive service from reception to departure made the experience memorable. The Waygu steak was cooked expertly and my favourite cut the ribeye was cooked perfectly.
The martini was mixed perfectly and extra olives was offered almost instantly. Well done!
