Most "typical" NY law firms offer similar benefits. Salary is VERY standardized, and bonuses, except for a few outliers, are also standardized.
Health benefits are standard, although the "benefit" ranges from firm to firm. Some firms offer very attractive plans with associates paying a low % of the premium (e.g., the firm pays may be up to 90%). At my firm, I pay about $100 a month for a pretty decent HMO. There is a PPO plan that is offered as well (for about 75% more). Dental and vision are also pretty typical and much cheaper (like $10-15 a month). Firms are likely to offer Flexible Spending Accounts (pre-tax dollars for co-pays and other qualified medical costs).
Most firms provide Long Term Disability and Accidental Death insurance and have attractive premiums for life insurance policies.
While most firms don't match 401k contributions, many firms have attractive 401k plans that allow you to invest in "brand name" mutual funds that .
There are also pre-tax commuting plans and parking plans (i.e., subway costs are pre-tax dollars as opposed to post-tax dollars - same with parking up to a certain amount).
Access to private banking is also rather common. Typically you don't pay fees for standard services, i.e., no fees on money orders or for ordering checks, better customer service, etc.
If the firm is large enough, you're likely to also see subsidized cafeterias in the office. Many firms have health club discounts (the scope and actual benefit vary pretty widely though).
