While lysine in the diet is considered safe, excessive doses may cause gallstones. There have also been reports of renal dysfunction, including Fanconi syndrome and renal failure. Talk to your doctor before taking supplemental lysine if you have kidney disease, liver disease, or if you are pregnant or breastfeeding.
Well I dont know about off premise sales, but on premise runs about like this...these are the general cost of sales numbers. Liquor 13%-17%. Beer (bottles)26%-31%. Beer (draft) 18%-26%. Wine-30%-47%. So the gross margin would be the reverse. Liquor 83%-87%.
Most operators simply look at the average pour costs in the industry or at their previous annual cost percentages. On that basis, most operators are happy if their liquor pour cost is around 15%, draft beer in the neighborhood of 20%, bottled beer close to 25% and wine between 30% - 40%. But even if a barâs cost percentages come close to these arbitrary targets, they may still be too high.
